RAILWAY-TIE PLATE.

SPECIFICATION forming part of Letters Patent No. 510,047, dated December5, 1893. Application filed April 24, 1893. Serial No, 471,663. (Nomodel.)

To all whom it may concern.-

Be it known that I, WILHELM PFEFFER- KORN, a citizen of the UnitedStates, residing at Johnstown, county of Cambria, State of Pennsylvania,have invented a new and useful Improvement in Railway-Tie Plates, ofwhich the following is a true and exact description, due reference beinghad to the accompanying drawings.

My invention relates to an improved form of brace tie plate forrailroads and has for its object to provide a plate which shall bestrong and at the same time constructed with the minimum amount ofwasted material.

Referring to the drawings Figure 1 shows a tie plate embodying myinvention. Fig. 2 is the blank from which the plate is formed and Fig. 3illustrates a way they might be out from a sheet With the minimum amountof waste.

The method of forming the plate is as follows: The flat plate shown inFig. 3 having been cut up as shown by the dotted lines the blanks thusformed have the piecesa andbFig. 2 removed by any suitable means aspunching or if desired they may be punched directly from the initialplate. The blank is then bent up in the shape shown in Fig. 1 theportion d folding at c and forming the brace of double thickness d. Theslot 1) provides a space for the rail flange to enter. The lug f whichforms a clamp for the other flange of the rail and the holes h and itare preferably not formed until the last thing as the lug f and hole isshould bear a certain relation to the edge of brace d, the rail beingclamped between them. The holes h provide means for spiking the plate toa tie beneath and the hole it permits a spike being driven so as to bearagainst the flange of the rail and thus lock the plate and prevent itbecoming loose.

The blanks shown in dotted lines in Fig. 3 mightbe bent up as shown inFig. 1 and a and b then removed, but I prefer the former method.

By this method of construction, I secure a brace of double thickness andconsequently increased strength.

Having thus fully described my invention, what I claim, and desire toprotect by Letters Patent, is

1. A tie plate for railway rails having a vertical brace adapted toengage the web of the rail said brace being formed by folding togetherthe central portions of a plate of metal the sidesof which form the baseof the tie plate substantially as described.

2. A brace tie plate for railway rails having a central rail braceformed of a piece of metal bent double as described, slot b for theentrance of one rail flange and lugffor engaging the opposite flange.

3. The method of forming a brace tie plate which consists in forming ablank substantially as shown in Fig. 2, then folding together thecentral portion at right angles to the side portions and forcing theside portions in contact with each other.

4. The method of forming a brace tie plate from a blank having a centralportion adapted to form the brace and two side members, which consistsin folding together the central portions at right angles to the sidemembers and forcing the side members in contact with each other.

In testimony whereof I have affixed my signature in presence of twowitnesses.
